v3dv/pipeline: don't clone the nir shader at pipeline_state_create_binning

At that point we didn't call all the v3dv lowerings. So the reference
nir shader used to call the v3d compiler could be different.

Note that at that point the nir shader is only available for internal
shaders (like gs multiview).

This specifically affected multiview tests that wrote gl_PointSize, as
the nir shader for the geometry shader were wrongly exposing
per_vertex_point_size as false, as we were basing our check on the
nir_shader_info, and that was gathered calling nir_shader_gather_info
at pipeline_lower_nir.
